Go anywhere and you're liable to see the same, but I would phrase it, "are users of alcohol along with other drugs and even pot." Of course, all are users of coffee, too. The mere use of a substance by a criminal does not mean that criminal behavior was caused by the substance. Correlation is not causation. I'm sure you've heard that before.
Cannabis is linked to very little, except in studies commissioned by those who profit from cannabis remaining illegal. In those studies, the raw data is masked (not available), the statistical methods are likewise. All we see is results. In most of the independent studies, all of which indicate little problem linked to cannabis, the data and methods are accessible.
Pot is as addictive as coffee or chocolate. If one likes it then one misses it when it's not available, but not to the point of withdrawal.
Freedom is the right to enslave yourself to anything you want to, so long as you don't harm anyone else. If you do and you do, then that one act of harm is punishable.
Nothing conservative at all about illegal drugs.
Nothing is liberal at all about illegal drugs, either. They are inanimate objects. The liberal and conservative aspects are in the FREEDOM of the individual to determine his own destiny, whether it be low or high. That is conservative, and its prohibition is liberal.
Where, in the book from which we draw our law and morals (the Bible), is cannabis prohibited or deemed immoral?
